Abstract

A fan 30 for mounting at one end of the armature of an electric motor comprises a ring portion 40 of moulded thermoplastic material supporting an annular plate 42 with integrally formed fan blades 46 in axial alignment with exhaust vents formed in the housing of the motor. The fan blades 46 extend radially across a face of the annular plate 42 remote from the ring portion 40 and extend into the annulus of the plate. The blades 46 are grouped and centered on the winding tunnels of the armature with the axially outer edges of the blades of each group joined together by a radial wall 50 within the radial spacing of the annulus of the plate 42 but axially spaced therefrom.
